BMI在食物选择和能量摄入方面的特定差异被认为是调节味觉的因素。然而，身体成分和脂肪味道敏感度之间的联系是有争议的。这项研究的目的是研究身体成分、饮食摄入量和四种脂肪刺激(油酸、石蜡油、菜籽油和掺有油酸的菜籽油)的检测阈值之间的关系，这些刺激可以通过味觉和/或质地线索感受到。在30名参与者中，以重复测量设计在12天内确定了脂肪检测阈值。通过测量参与者的BMI、腰围和腰臀比来检查体重状况。通过几份问卷和12份不连续的24小时食物日记来评估习惯性食物摄入量。在这项研究中，脂肪检测阈值与富含维生素和纤维的食物摄入量之间存在负相关。此外，高脂肪食物的摄入量与脂肪检测阈值之间存在正相关。没有观察到由于BMI或腰臀比的变化而导致脂肪检测阈值的差异。这些发现表明，经常摄入高脂肪食物可能会降低个人对脂肪的感知反应，这可能会导致长期过量的脂肪摄入。(C)2017爱思唯尔有限公司。保留所有权利。
BMI-specific differences in food choice and energy intake have been suggested to modulate taste perception. However, associations between body composition and fat taste sensitivity are controversial. The objective of this study was to examine the association between body composition, dietary intake and detection thresholds of four fatty stimuli (oleic acid, paraffin oil, canola oil, and canola oil spiked with oleic acid) that could be perceived via gustatory and/or textural cues. In 30 participants, fat detection thresholds were determined in a repeated measurements design over twelve days. Weight status was examined by measuring the participants' BMI, waist circumference and waist-to-hip ratio. The habitual food intake was assessed via several questionnaires and twelve, non-consecutive 24-hour food diaries. In this study, a negative correlation was found between fat detection thresholds and the intake of food rich in vitamins and fibre. Moreover, a positive correlation was identified between the intake of high-fat food and fat detection thresholds. No differences in fat detection thresholds were observed due to variations in BMI or waist-to-hip ratio. These findings indicate that a regular intake of fatty foods might decrease an individuals' perceptual response to fats which might lead to excess fat intake on the long term. (C) 2017 Elsevier Ltd.
